Mine used to be different one side to the other (can't remember which?), not so much since I changed the exhaust crossover for a more 'Spaghetti' style with a more direct flow but my 916 runs one side hotter/bit more pressure at idle which I put down to the pipe routing - rear cylinder pipe does a 'U' bend downwards to lengthen the pipe to about the same as the front.
So unless it's running much richer/leaner on one than the other then I think it all balances out fairly well at speed...
